A problems of constructing the ytterbium quantum measure of frequency and sensing the collisional shift of the ytterbium hyperfine structure (HFS) lines in a medium of bath (He) gas are studied. Relativistic approach is used in calculating the inter atomic potentials, oscillator strengths, HFS collision shift and broadening for ytterbium atom in a medium of helium bath gas.

Diamagnetic shift and singlet-triplet mixing of 6snp Yb Rydberg states with large radial extent

Jörg Neukammer, Herbert H. Rinneberg, U. Majewski

The diamagnetic shifts of the ${m}_{J}=0$ and ${m}_{J}=\ifmmode\pm\else\textpm\fi{}1$ components of $6snp ^{1}P_{1}$ ( $n=40,55,70,85,100$ ) and $6s55p ^{3}P_{0, 1}$ Rydberg states of $^{172,\phantom{\rule{0ex}{0ex}}174}\mathrm{Yb}$ have been measured in external magnetic fields up to ≌3 kG by high-resolution three-photon spectroscopy. The diamagnetic shifts have been analyzed to yield the singlettriplet mixing due to spin-orbit interaction. At $n=40$ , the singlet-triplet mixing derived from diamagnetic shifts and hyperfine-structure data are in excellent agreement.The diamagnetic shifts of the ${m}_{J}=0$ and ${m}_{J}=\ifmmode\pm\else\textpm\fi{}1$ components of $6snp ^{1}P_{1}$ ($n=40,55,70,85,100$) and $6s55p ^{3}P_{0, 1}$ Rydberg states of $^{172,\phantom{\rule{0ex}{0ex}}174}\mathrm{Yb}$ have been measured in external magnetic fields up to ≌3 kG by high-resolution three-photon spectroscopy.
